摘　　要：针对现有焦化废水NH_3-N和COD严重超标问题,本文提出了一种新的焦化废水处理工艺,即厌氧——缺氧/好氧工艺(简称A—A/O工艺)。中试研究表明:该工艺对焦化废水处理具有明显效果,所有出水指标均满足排放要求,并留有相当余地,达到了对NH_3-N、TN和有机物同时控制的目的。用A—A/O工艺处理焦化废水,是一条既经济又便于现有焦化厂改造的、解决焦化废水污染问题的有效途径。Experiments have been carried out in a pilot plant for reducing COD and NH3-N simutaneously in coke plant wastewater by using anaerobic-anoxic and oxic(A-A/O)process. Results have shown this process to be a cost-effective way for coke plant wastewater treatment. All the parameters of the effluent including COD,NH3-N and others can meet the national discharge standards issued.
